IBM set to supercede Flash with superfast, high capacity, low cost Racetrack memory
April 11, 2008 Nanotechnology was more science fiction than fact when Dr. Eric Drexler released his seminal 'Engines of Creation: the Coming Era of Nanotechnology' in 1986. 20 years later, this revolutionary discipline, which focuses on the manipulation of matter at an atomic or sub-atomic level, is starting to bear fruits in a vast array of bleeding-edge technologies. With nanotech innovations spurring the latest advances from solar energy capture that works in the dark, to long-range, high-power, quick charging batteries for electric cars, to fog-free glass and smart self-thermoregulating fabrics already maturing as viable technologies, the latest advances in nanowire data storage from IBM seem set to thrash both hard drives and flash memory at their own games. It'll be incredibly fast, virtually indestructible thanks to no moving parts, its capacity will be absolutely enormous, it'll use next to no power and produce next to no heat - and it will be 100 times cheaper per byte than flash memory. What's more, IBM says the public debut of this amazing "Racetrack" memory "could be closer than you think." (read more...)
The Nokia Morph Concept Phone
Nanotechnology looks set yield some seemingly magical functionality in the near future, and a recent concept product from Nokia puts most of the technologies that will be viable for handhelds within the next decade into one fascinating instrument. The Morph does just that, being flexible so that it can change shape from candy bar phone to bracelet. It’s also transparent, has self-cleaning surfaces, can sense and observe and even harvest energy from the local environment. The result of a partnership between Nokia and the University of Cambridge, the Morph went on display this week alongside the remarkable "Design and the Elastic Mind" exhibition at The Museum of Modern Art (MoMA) in New York.

Researchers developing solar technology that works at night
January 4, 2008 Idaho National Laboratory (INL) reports that research conducted in conjunction with partners at Microcontinuum Inc. (Cambridge, MA) and Patrick Pinhero of the University of Missouri is promising a method for developing cheap solar energy technology that could be imprinted on flexible materials and still draw energy after the sun has set. The technology uses a special manufacturing process to stamp tiny square spirals, or “nanoantennas”, of conduction metal onto a sheet of plastic and the team estimates individual nanoantennas can absorb close to 80 percent of the available energy in comparison to current commercial solar panels which usually transform less that 20 percent of the usable energy that strikes them into electricity – this is even more impressive than the 30% conversion rate offered by the recently discussed development of nano flakes.

Nanotech breakthrough promises single-atom data storage and molecular computers
IBM today announced two major scientific achievements in the field of nanotechnology that could one day lead to new kinds of devices and structures built from a few atoms or molecules. Such Lilliputian, atomic-scale devices might be used as future computer chips, storage devices, sensors and for applications nobody has imagined yet. The work will be unveiled tomorrow in two reports being published by the journal Science. In the first report, IBM scientists describe major progress in probing a property called magnetic anisotropy in individual atoms. This fundamental measurement has important technological consequences because it determines an atom’s ability to store information. Previously, nobody had been able to measure the magnetic anisotropy of a single atom. (read more...)

IBN Nano-Bio Kits demonstrate bioengineering and nanotechnology through interactive experiments
March 12, 2007 One of the problems with new technologies advancing so quickly is that the classroom can be left a long way behind. Recognising this, Singapore’s Institute of Bioengineering and Nanotechnology (IBN) is arming teachers with new tools to revitalize their teaching of science in the classrooms. IBN has launched a series of educational Kits to help secondary school and junior college teachers inject cutting-edge concepts in their laboratory lessons. Aimed at students between the ages of 15 and 19, the IBN Nano-Bio Kits feature interactive experiments and lessons on practical applications in nanobiotechnology, drug delivery and medical devices. The first three Kits in the range include the Biological Fuel Cell Kit, the Thermo-responsive Hydrogel Kit, and the Dielectrophoresis Chip Kit, and they come equipped with lesson plans, background readings, experimental components and instructions, as well as worksheets and quizzes. Teachers are also provided with worksheet answers, experimental instructional videos, and slides to help them plan lesson modules based on the scientific topics relevant to each Kit. Video on the kits here. (read more...)
Nanotech thermoregulator fabric developed
October 17, 2006 It sounds like the type of product found in a sci-fi novel, but French fabric house Avelana and Roudiere, has created a “thermoregulator” fabric line, which absorbs ambient thermal changes and offers a garment which keeps its wearer at a similar temperature regardless of the weather – much cooler in summer or much warmer in winter. The new Klimeo process involves the application of a treatment to pure or mixed wool fabrics and is ideal for traditional woven textile markets, and is beneficial for knitwear used in active outdoor and sports markets, as well as other next-to-skin applications. Though it adds remarkable new qualities to fabrics, Klimeo is invisible to the naked eye, and does not change the aesthetics, fall or texture of fabrics, and retains its new properties even after machine washing and dry cleaning.To create Klimeo, microcapsules are grafted to the fabric. These capsules change their phase depending on the temperature. The substance in the microcapsules is solid when you are in a cold environment and it is liquid when you are in a warm environment.

Nanotech promises the first viable alternative to batteries in 200 years
February 14, 2006 Almost everything we use requires electrical storage via a battery - computers, cell phones, cars, personal entertainment devices and much more – and as compelling functionality has increased in the digital age, so too has our reliance on the traditional battery which has changed little since it was developed by Alessandro Volta in 1800. Now, work at MIT's Laboratory for Electromagnetic and Electronic Systems (LEES) holds the promise of the first technologically significant and economically viable alternative to conventional batteries in more than 200 years. Using nanotube structures, the LEES invention promises a significant increase on the storage capacity of existing commercial ultracapacitors by storing electrical fields at an atomic level. The new LEES ultracapacitors could replace the conventional battery in everything from the smallest MP3 players through to electric automobiles and beyond, yielding batteries with a lifetime equivalent to the product they power and recharging times inside a minute. Most significantly, they promise a much smaller and lighter “battery”, and will be an enabling technology for many new concepts such as electric bicycles with the “burst” peak power of a motorcycle, or electrical trams with the capacity of a train but without the infrastructure. In automotive terms, they raise the possibility of an integrated starter/generator and the capability of ultra-efficient regenerative braking systems. The work was presented at the recent 15th International Seminar on Double Layer Capacitors and Hybrid Energy Storage Devices and the LEES “batteries” could reach market within five years. A potentially disruptive technology! (read more...)
Underfoot insulation using nanotech
December 21, 2005 The human body needs warmth and the areas in which we feel the cold first are naturally enough those which are at the extremities – hands and feet. The feet are particularly vulnerable in arctic climates as they are continually in contact with very cold surfaces. Accordingly, the advanced nanotech underfoot insulation offered by ToastyFeet insole liners from Polar Wrap. Most insulation requires loft but when you step on it, it gets compressed and loses its loft and therefore its insulating power. Aerogel doesn't require loft as it contains nanometer-sized pockets of air that can maintain thermal protection and shape even when you step on it. In partnership with NASA, this same flexible aerogel technology is being developed for next generation space suits but you can get it now and keep your feet toasty warm. We've written about numerous applications for aerogel technology including a translucent roofing system and about the origination of the world's lightest solid. (read more...)
Nanotech coating to cure fogging permanently
December 12, 2005 Nanotachnology looks set to permanently fix the problem of fogging glass, with the news that a team of MIT scientists has developed a silica nanoparticle polymer coating for glass or plastic that creates a permanent non-fog surface. When commercialized sometime in the next few years, the technology will find immediate application in products such as eyeglasses, helmet visors, camera lenses, skiing goggles, bathroom mirrors and shower screens, but it will be in our cars that we will most likely first encounter the technology. Driving is a sight-response game and if you can’t see, you’ll lose. Not surprisingly, the Defense Advanced Research Projects Agency (DARPA) was one of the major funders of the project as having a foggy windscreen makes you vulnerable in battle as well as on the roads. When a cold surface suddenly comes into contact with warm, moist air, thousands of tiny water droplets condense on it, scattering light in random patterns and causing the surface to become translucent. The coating prevents this by attracting the water droplets and reducing their contact angles with the surface. As a result, the droplets merge into a uniform, transparent sheet rather than forming countless individual light-scattering spheres. Nanotechnology will also enable the same coatings to have superior anti-reflective properties that reduce glare and maximize the amount of light passing through (good for greenhouses and solar cell panels).
